Useful technology courses/certificates?

hi,
well im new to techspot, was browsing the internet thats how i come to know about it. well i need help to start a course in IT. actually i have done my first degree in electronics engineering and then my second one in mobile computing and i have a passion to learn about networks and computers but unfortunately have no commercial experience in an IT industry so far. i have 2 years gap now in my last degree but have done work in customer services. well im looking to start and put my foot down in IT industry now, dont matter even to start off with a samller role. with my short research on all the courses i made my mind up to start compTIA A+ then after will do my network + i get intpo the job market. can any one suggest are the courses helpful in filling up the gap and move into an IT job market? and how beneficail are those courses?
thanks
